NSA re-releases Boak’s Lectures

I’m a fan of Boak’s Lectures – they cover the fundamentals of military cryptography just before the information revolution.David Boak developed the lectures for the National Security Agency’s Cryptologic School.

Even though the lectures are from the ’60s and ’70s, they remain relevant to today’s cybersecurity threats. Cryptographic techniques that were classified Secret in Boak’s work are prominent in modern commercial cryptosystems. A sanitized version of Boak’s Lectures (Vol 1, Vol 2) was released in 2008.
